Abstract:
      The relationship between leaf area index, photosynthetic rate and yield with different maize populations in the wheat/maize intercropping was studied. The results showed that the curves of LAI and Pn of different maize populations were parabolas, and the correlation between Pn and LAI was significantly positive. So improvement of the photosynthetic rate could increase maize yied. In two intercroppings, the average photosynthetic rate and the maize yied in A1D3 was the largest, while those in A2D2 was the second.
